HERBERT MGNULTA, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO RATEAU STEAM REGENERATOR COMPANY, OF NEW YORK, N. Y., A CORPORATION OF WEST VIRGINIA.

T 0 all whom it may concern i i I Be it known that I, HERBERT MONULTA, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Steam- Regenerators, of which the following 15 a specification.

The invention relate to apparatus for use in the regeneration of steam which is supplied thereto intermittently and often 1 n variable quantities and which apparatus 1s designed to deliver steam therefrom at any time regardless as to whether or not steam is being supplied to the apparatus at the particular instant of withdrawal.

The invention furthermore particularly relates to a regenerator in which water 1n finely divided form is delivered into the path of flowing steam and carried to a place where it can be collected into a large body of regenerating liquid so that a comparatively large quantity of steam can'be given off from the liquid when the supply coming into the regenerating apparatus 1s less than the amount of steam whlch is being withdrawn from the regenerating apparatus.

As showing specific embodiments of my invention reference is made to the drawings, in whichv Figure 1 shows in section one form of the regenerating apparatus. Fig. 2 shows an other form. Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 1 looking in the direction of the arrows. Fig. 4 is a vertical sectional View taken on the line 4- of Fig. 2 looking in the direction of the arrows, and Fig. 5 shows the manner in which the piston for regulating the flow of water in the regenerating chamber can be controlled by a piston valve that is operatively connected to a movable vane or valve member located in the path of the incoming steam.

Throughout the specification and in the drawings the same reference character refers to the same Part.

In Fig. 1 there is illustrated a regenerating apparatus comprising a steam receiving chamber 1 provided at the upper portion with a steam inlet 2, a liquid holding or regenerating chamber 3, provided at the upper portion with steam outlets 4:, a spray box 5, and an eduction pipe 6 passing Specification of Letters Patent.

through the spray box and connecting the steam recelvlng chamber with the upper interior portion of the liquid holding chamber. There is located in the steam receiving chamber 1 a funnel shaped member 7 leadsaid pipe. The spray box 5 is provided with an opening 9 communicating with the interlor of the regenerating or liquid holding chamber and this opening is controlled by a valve 10. Located within the funnel shaped member 7 is a movable vane or valve member 11 so mounted that its position is dependent upon the amount of incoming steam passing through the funnel member 7 on its way through the eduction pipe. It will be observed that there is an arm and link connection ll between the movable member 11 and the valve 10 whereby as the former is caused to move by the steam flowing through the funnel shaped portion the valve 10 will be positioned so that the amount of liquid flowing into the interior of the spray box and from thence into the eduction pipe by means of the numerous openings 12 in the walls thereof will be dependent upon the amount of steam passingthrough the eduction pipe at that time. It will also be observed that the openings 12 are comparatively small and they therefore deliver liquid in a finely divided form into the steam flowing along said pipe and the consequence of this is that the steam and water are intimately mixed whereby the water will absorb heat from the steam and will be carried by the steam up through the pipe where it can again mingle with the water in the regenerating or liquid holding chamber so as to give off steam when the pressure in said chamber is decreased by the withdrawal of steam therefrom in excess of that being supplied. In the form shown in Fig. 1 there is also provided at the lower end of the funnel shaped portion 7 a movable bottom or drip member 13 which permits any liquid that may collect in the bottom thereof to be drained into the lower part of the steam receiving chamber from which it can be removed by an overflow or drain 14.

Inthe form illustrated in Figs. 2 and 4c there is disclosed liquid holding or regenerating chambers 3, 3; spray box 5, 5; eduction pipes 6, 6 and the funnel shaped portions 7 leading thereto. These parts are all shown in duplicate and are all operatively connected in substantially the manner above described in relation to Figs. 1 and 3 to a common receiving chamber 1. In this form however the movable bottom at the lower portion of the funnel shaped member 7 has been omitted and instead of utilizing the arm and link connection between the valve 10 between the regenerating or liquid holding chamber and the spray box, and the movable member or valve 11, there is utilized a cylinder 15 having therein a piston 16 connected by means of a rod 17 to the valve 10 and the position of the piston 16 in the cylinder is dependent upon the position of a piston valve 18 which is operatively connected to the movable vane 11 by rod 19. From an inspection of Figs. 2 and 5 it will be seen that the steam cylinder 15 is connected at its opposite ends to a live steam supply 21 and that the piston valve 18 is located in a casing 22 open to the atmosphere by pipe 23 and connected to the cylinder 15 by a series of pipes 24, 25, 26, 27 and 28, leading from different longitudinal sections in the cylinder to difierent longitudinal sections along the casing. Now as the cylinder 15 is supplied at its opposite ends with live steam through the pipes 21 it will be apparent that when the piston valve 18 is caused to move from the dotted to the full line position shown in Fig. 5 by the movable vane 11* a difierential pressure on opposite sides of the piston 16 shown in dotted lines will be efiected since the pipes 26 and 23 and the cutout portion 29 of the valve 18 form a direct exhaust and this differential pressure will cause the piston 16 to move to the position shown in full where it can close the opening leading to the pipe 26 and when this opening is closed it will be apparent that the pressure on opposite sides of the piston 16 will be equalized and the piston will stop in this position. By the construction just described the position of the valve controlling the opening between the regenerating chamber and the spray box can be made dependent upon the position of the movable member 11 controlled by the flow of steam passing thereby.

It will also be apparent that the funnel shaped portions 7 and 7 the eduction pipe and the spray box are all located within the cylindrical wall which defines the steam receiving chamber and the liquid holding chamber and one phase of the invention relates to this structure which is exceedingly simple and compact but all phases of the invention are not necessarily limited to this form.

It is obvious that the structures shown in Figs. 1 and 2 might be utilized in a regenerator having one or two or more liquid holding chambers and also that various other forms and modificatlons may be made without departing from the spirit and scope of the invention.

I claim as my invention 1. A regenerating apparatus comprising in combination a liquid holding chamber provided with a steam outlet, a steam receiving chamber, an eduction pipe leading from the receiving chamber to the upper portion of the liquid holding chamber, a

spray box within the liquid holding chamber and having an opening in its walls through which water can pass from the holding chamber into said spray box and means controlled by the steam passing through the eduction pipe to regulate the flow of liquid through said openings, there being communicating openings leading from the interior of said spray box to the interior of the eduction pipe.
